We also have Frontier fiber 500. The price has gone up a few times over the past 3 years. Most recent bill was 69.99. I called their retention department, and they lowered our bill to 39.99 for the next year.
Thanks for all the tips and tricks for canceling my Optimum service. I woke up this morning to an email and voicemail from Optimum notifying me that they received my returned equipment and credited my account for any unreturned equipment fees. Good riddance!
